In a televised speech broadcast to his supporters to mark "Al Quds" day, Nasrallah said Israel has a network of agents working in Lebanon who are responsible for the political killings.

Nasrallah, whose group leads the pro-Syrian opposition to Lebanon's U.S.-backed government, also warned the parliamentary majority against picking a president of their own to run the country if talks with the opposition failed, and called for polling the general population on their choice if the lawmakers fail to reach agreement.

The Hezbollah chief said attacks against members of Lebanon's anti-Syrian parliamentary majority in the last two years have automatically drawn condemnation from that coalition against Damascus, Hezbollah's ally, and that was the reaction the killers expected, Nasrallah said.

"The hand that is killing is Israel's," he told thousands of supporters who occasionally interrupted his speech with roars of approval.

By the way, this Haaretz article ends with an inexplicable zen koan: "Nasrallah ended the speech with a quote from the Koran which relates to the Children of Israel." The reader must meditate upon that phrase for many years to discover meaninglessness of whatever Nasrallah said.
